STILLWATER, Okla. - Texas Tech limited Oklahoma State to just two hits and then connected on three home runs en route to a 10-0 run-rule victory in the Big 12 Conference opener Thursday evening at Cowgirl Stadium.

The victory marks the second-straight year where the Red Raiders (27-12; 1-0) opened league action with a run-rule win. It was also the largest margin of victory for Tech ever in the series with Oklahoma State (22-14; 0-1).

"You don't get many days like this in the Big 12 but we'll take it," Tech head coach Shanon Hays said. "We hit the ball really well against a good pitcher. Oklahoma State has a good ball club, so we'll have to play well the rest of the way to win the series."

Mikey Kenney connected on two solo home runs - a leadoff shot to right center in the third and then a one-out line-drive deep over the left-field fence in the fourth. It was the third multiple home run game for Kenney this year, giving her 11 long balls on the season.

Her third-inning shot was the first of four runs for Tech in the inning as Adriana Perez followed with a three-run homer to left field. She finished with five RBI in the game as she added a two-run single in the sixth.

Tech had four players finish with at least two hits, led by Sandy James, who went 3-for-4 with a RBI single to put the Red Raiders on the board in the first inning. Kenney finished 2-for-2 with a walk and hit by pitch while Perez went 2-for-4 and Lexie Elkins had a 2-for-3 day in her first-ever conference game.

In the circle, Cara Custer shut down the OSU offense with just a pair of singles - one in the second and then another to lead off the fifth inning. The right-hander allowed just three base runners and struck out three before giving way to Brittany Talley, who tossed a perfect sixth inning to complete the rout.

Kat Espinosa (12-7) suffered the loss for OSU as she surrendered all 10 runs, six of which were earned, off nine hits while striking out six. She also walked three and plunked one.

Tech and Oklahoma State will play game two of the three-game set at 5:30 p.m. Friday evening at Cowgirl Stadium.
